To improve the transport and intercepting capability of interceptor considering the relative distance and velocity between target and interceptor

etc

the zero-effort-miss model of interceptor

the internal ballistic model and the mass & size model of trajectory-control engine were established to optimize the trajectory-control engine. The genetic arithmetic combined with Powell method was also adopted in the optimization design of trajectory-control engine. The zero-effort-miss eliminated by trajectory-control engine could improve not less than 17.9% as proved by the optimization design case

and the influence caused by uncertain factors was more explicit

so the method might be applied to the optimization design of interceptor.
